SPECIFICATION forming part of Letters Patent No. 340,806, dated April 27, 1886.

(No model.)

.To @ZZ whom it may concern.-

Be it known that we, DANIEL T. MONTEL and JOHN B. CARTER, of Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Ventilation of Houses; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which torni part of this speciiication. Our invention relates to an improvement in the ventilation of buildings; and it consists in a metallic flue which is provided with registers for Ventilating the rooms, guards placed iu the line, and a. stove-pipe which is placed inside of the iue and connected with the various rooms, all of which will be more fully described hereinafter.

The object of our invention is to provide a double flue which is made wholly of metal, and which is connected with each ot' the rooms, one above the other, whereby each room can be ventilated thoroughly without the slightest danger of any of the foul air or gases from one of the lower rooms passing up through the registers in any of the rooms above.

In the accompanying drawings, Figure 1 represents a vertical section of a metallic register embodying our invention. Fig. 2 shows a modification.

A represents a metallic iiue,which is placed inside of the chimney or in the wall, as may be desired. Through the inner side of this flue in each room there is lnade an opening, B, for ventilation, and each one of these openings is controlled byv a register, O, of any suitable construction. These openings,which are made near the iloor in each room, enable all the 'foul air and gases which may have settled near the floor to be drawn oft' through the flue at will by opening or closing the register. In order to prevent the `foul air and gases which pass into the flue `from one of the lower chambers from passing up through the register into one of the rooms above,a guard,

' G, is placed in the ue below each opening B,

would be liable to do if the guard G were not used. This opening B can also be used to admit fresh air into the rooms when the air is cool enough to descend througlnthe iiue. Placed in the center of this Hue is a vertical stove-pipe, I-I, which is connected by the small pipes I with each oneof the rooms past which the fine A passes. This pipe I-I is made perfectly tight so far as the line A is concerned, and hence no smoke or gases arising from the products of combustion will interfere with the air in the ilue, and thus prevent a perfect ventilation. During the winter, or when a stove is in operation and connected with this pipe H, the product-s of combustion passing through this pipe I-I will heat the air in the due, and thus cause an upward draft through the flue,which will ventilate thoroughly each one of the rooms in which the register is open.

will be seen that a double flue constructed entirel y from metal is used, and one which can be produced much more cheaply than one made from bricks alone, or from brick and tiles, which have heretofore been used for this purpose. After the dimensions are known the iiue can be readily made and placed into position ready for use, and at comparatively very little expense. This iiue carries oft' not only products of combustion, but ventilates each room, and that without allowing the foul air and gases of one room from passing into the room or rooms above it.

Where the flue and ventilator are to extend directly up through a ceiling, the flue and stove-pipe H will be constructed as shown in Fig. 2. In this case the stove-pige IfI will be ,placed in the center of the ilue, and the ilue-v pipe will vbe supported by the perforated plate P, which is secured in position in any suitable manner. Through this plate are made suitable ventilating-openiugs, which are controlled by the valves or valve Q. These valves may open either upward or downward, and may be held in any desired position by means ot counter-weights or any devices which will answer for this purpose. l

Ve do not restrict our invention to any particular devices for either operating the valves or holding them in any desired position.

From the construction above described it IOO Ve are aware thatastove-pipc fine has been H I, combined and arranged substantially as 1o placed inside of :L Ventilating-pipe, and that described. the Ventilating-pipe has been provided with In testimony whereof We affix oursignatnrcs means for Ventilating the rooms with which it in presence of two Witnesses.
